They get in the way of parking spots. The steel cages must rule supreme.

Real answer is probably that they'd be used in addition to trees, designed to fit in places unsuitable for a tree.
This. Trees (especially large ones) are a pain to irrigate properly, might not be drought-resistant, grow very slowly until they reach their full potential at removing CO2, interfere with infrastructure that we humans are used to (piping, electricity, telco), roots break up pavements, branches can be a hazard after storms, fruit might attract rats, ...
I'm very much pro trees (despite what I've listed in the first paragraph), but I'm sure there are places in cities where you can't plant trees but could put up algae tanks.
If you understand German (specifically Austrian dialect) you might like this podcast episode about challenges and methods to overcome them in the context of greenery in the city of Graz:
Simple Smart Buildings: Bäume in der Stadt

TL;DL of this episode: it's not as simple as "just plant more trees".

This just makes me think it’s an aquarium that needs to be cleaned.
even your trees will be slop. nice.
Upkeep costs. Oh, wait.
What happens when one of these breaks and drains into the sewer system? Algae blooms cause noxious odors and would proliferate quickly in the nitrogen-rich environment of human waste water, potentially building up as clogs in the sewer lines. And if the system drains into a natural body of water, the algae can have devastating toxic effects on the natural wildlife. If it doesn't drain and instead gets recycled, then the water treatment process becomes much more difficult and expensive.
Has the manufacturer even calculated how much energy is needed for production and how long it will take for the corresponding CO2 emissions to be amortized?
We are living in strange times...
And trees that are planted in cities are not seeded. They are grown in a forestry until they reach a certain height. And then dug up with machines transported with machines and then planted with machines. The CO2 produced to plant a single tree also takes quite a while to be absorbed by that tree.

Insert random copypasta about biotech breakthrough that turns water and CO2 and nutrients into sustainable building materials which sounds like space age technology but it's just trees
trees are not as profitable
